I don't think that that will work reliably.

alsactl opens sound devices controlled by the sound card driver.  We
want both:

* "alsactl restore" only after the sound card driver loads
* "alsactl restore" every time the sound card driver loads

The only reliable way to guarantee both (that I can think of) is to hook
the module loader so that it runs "alsactl restore" after loading the
sound card driver.

As an experiment I removed my sound card driver (snd_cs46xx) and hid the
.ko file.  Then I tried running "alsactl restore".
